Yes, but I think one thing that is interesting here is that these Graviton 2 instance types also offer, for example, better IO throughput or storage/$ even though the CPU architecture doesn't obviously affect that (i.e., it's not like you get access to a new source of quality NAND chips to build SSDs when you switch your CPU). Another thing I found interesting was that the porting process was painless for this native application. There are lots of examples of quick wins on Graviton for interpreted or bytecode/JIT'd languages where the runtime exists on Arm and the software just works, but porting a complex native application would seem to pose more problems. In our case, however, it was quite straightforward (more than I would have expected).
